Besides the changes in light levels, if you look carefully, the foreground is softer in the lighter pictures, or a bit sharper in the darker ones (look in to the granite block on the right and the grill on the left, specially between photos #4 and #5). I asume all pictures where focused at the same distance.

This could be a sign of a sticky aperture. According to EXIF all pictures where taken at f5.6. Looks like on the three that are brighter the aperture was wider.
